    oxide-qt vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.10
    - Ubuntu 14.04 LTS
    
    Summary:
    
    Several security issues were fixed in Oxide.
    
    Software Description:
    - oxide-qt: Web browser engine library for Qt (QML plugin)
    
    Details:
    
    A use-after-free bug was discovered in the DOM implementation in Blink. If
    a user were tricked in to opening a specially crafted website, an attacker
    could potentially exploit this to cause a denial of service via renderer
    crash or execute arbitrary code with the privileges of the sandboxed
    render process. (CVE-2015-1209)
    
    It was discovered that V8 did not properly consider frame access
    restrictions when throwing exceptions in some circumstances. If a user
    were tricked in to opening a specially crafted website, an attacker could
    potentially exploit this to bypass same origin restrictions.
    (CVE-2015-1210)
    
    It was discovered that Chromium did not properly restrict the URI scheme
    during ServiceWorker registration. If a user were tricked in to
    downloading and opening a specially crafted HTML file, an attacker could
    potentially exploit this to bypass security restrictions. (CVE-2015-1211)
    
    Multiple security issues were discovered in Chromium. If a user were
    tricked in to opening a specially crafted website, an attacker could
    potentially exploit these to read uninitialized memory, cause a denial
    of service via application crash or execute arbitrary code with the
    privileges of the user invoking the program. (CVE-2015-1212)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.10:
      liboxideqtcore0                 1.4.3-0ubuntu0.14.10.1
      oxideqt-codecs                  1.4.3-0ubuntu0.14.10.1
      oxideqt-codecs-extra            1.4.3-0ubuntu0.14.10.1
    
    Ubuntu 14.04 LTS:
      liboxideqtcore0                 1.4.3-0ubuntu0.14.04.1
      oxideqt-codecs                  1.4.3-0ubuntu0.14.04.1
      oxideqt-codecs-extra            1.4.3-0ubuntu0.14.04.1
    
    In general, a standard system update will make all the necessary changes.
